omfs: fix oops when file metadata is corrupted
A fuzzed fileystem image failed with OMFS when the extent count was used in a loop without being checked against the max number of extents. It also provoked a signed division for an array index that was checked as if unsigned, leading to index by -1. omfsck will be updated to fix these cases, in the meantime bail out gracefully.
